Execution failed for task ':buildDB2BotcImage' - docker

Question

System Info : Windows 10 Enterprise
Gradle Version 4.3.1
Docker Version 17.10.0-ce, build f4ffd25
I am getting an issue while doing gradle.build, Error I am getting
Unrecognized field "identitytoken" (class com.github.dockerjava.api.model.AuthConfig), not marked as ignorable (6 known properties: "serveraddress", "username", "auth", "password", "email", "registrytoken"])
at [Source: N/A; line: -1, column: -1] (through reference chain: java.util.LinkedHashMap["auths"]->java.util.LinkedHashMap["registry.au-syd.bluemix.net"]->com.github.dockerjava.api.model.AuthConfig["identitytoken"])
I have done some research and found this https://github.com/bmuschko/gradle-docker-plugin/issues/310 , and done some changes in my build.gradle but still i am getting this error.
The changes I have done in one of the part of build.gradle file :
Previously:
docker {
if (System.properties['os.name'].toLowerCase().contains('windows')) {
url = 'tcp://localhost:2376'
certPath = new File(System.properties['user.home'], '.docker/machine/certs')
}
registryCredentials {
url = 'https://maxrep01.swg.usma.ibm.com/'
username = 'username'
password = 'secret'
}
}
Changed:
docker {
if (System.properties['os.name'].toLowerCase().contains('windows')) {
if (new File("\\\\.\\pipe\\docker_engine").exists()) {
url = 'npipe:////./pipe/docker_engine'
}
else {
url = 'tcp://localhost:2376'
}
certPath = new File(System.properties['user.home'], '.docker/machine/certs')
}
registryCredentials {
url = 'https://maxrep01.swg.usma.ibm.com/'
username = 'username'
password = 'secret'
}
}
This is the only helpful link I am getting, but I am unable to get what is the issue is, my understanding is it is something related to windows 10, but as per the link the changes i have done should resolve the issue.
I am not sure what is wrong here?

Your problem is most likely related to Issue #921 of the docker-java project.
Hello, we got the issue, using latest version of "docker-java" while trying to load and parse DOCKER configuration file ("$HOME/.docker/config.json").
It doesn't accept the field 'identitytoken'. I have noticed that you have 'registrytoken' field, which have been used since DOCKER API v1.22 version for the same purpose. I checked documentation, it was renamed there into --> 'identitytoken' just in the next DOCKER API v1.23 version.
If waiting for a next docker-java version is not acceptable, it might help to tweak config.json to suit your needs.
